I keep having problems with LO on El Capitan. Trying to start it as a normal application by double-clicking the icon always gives me the “is damaged” warning—for both, latest 4.x and 5.x LO. If I start it from the command line, things seem to work just fine:
/Applications/LibreOffice.app/Contents/MacOS/soffice
Is that going to get fixed soon? Might be related to this one?
